What is the definition of the light year?
The light-year is the distance light travels in a year. Since this sometimes causes confusion, please note that a light-year is a unit of distance; NOT a unit of time. A light-year is approximately 9.5 x 1012 kilometers. (A light-year is defined to be exactly 9,460,730,472,580,800 metres.)
What is the order of increasing length of astronomical unit parsec kilometer and light year?
kilometer, AU (astronomical unit), light year, parsec.
Which unit of measurement represents the distance light travels in one year?
light-year
What is the longest light year?
A light-year is a measure of distance that a photon of light will travel in one year .
Is an astronomical unit larger than a light year?
No, an astronomical unit (AU) is the average distance between Earth and the Sun, approximately 93 million miles. In comparison, a light year is the distance that light travels in one year, which is about 5.88 trillion miles. Therefore, a light year is significantly larger than an astronomical unit.
What are similarities between leap year and light year?
Both contain the word "year," but are otherwise unrelated. A light year is a unit of distance, while a leap year is a correction to a unit of time.
Is there such thing as a leap lightyear?
Please note that a light-year is a unit of length, not a unit of time. It is the distance light travels in a year. An average value for the year is used for this purpose; thus, no distinction is made between normal and leap years. The average value, in the official definition of the light-year, is a so-called Julian year; from the Wikipedia: "In astronomy, a Julian year (symbol: a) is a unit of measurement of time defined as exactly 365.25 days of 86,400 SI seconds each."
Is a light year a unit of time True or false?
False the light year is not a unit of time it is a unit of distance true.
Is a light year a unit of a distance or a unit of a time?
Both
What is the similarities of light-year and leap year?
They are very different. Years are divisible by 4 are leap years, though if they are divisible by 100 and are not divisible by 400, then they are not leap years. A light year is a measurement of distance, not time. It is the distance that light travels in a year. It is about six trillion miles or nine trillion kilometres.
Higher unit of time is?
An era is a higher unit of time, as is a millenium, or century.
How old is mira the star in light years?
"Light-year" is NOT a unit of time. It is a unit of length or distance - the distance light travels in a year.
Does a calendar year equal a light year?
No. A light year is a unit of distance, not time. It is the distance light travels in a year.
How many hours is a light year?
This is an impossible conversion to make. A hour is a unit of time. A light year is a unit of distance, specifically, it is the distance light travels in a year.
Whats the distance traveled by light in a leap year?
366 light days, if you interpret leap year to be the entire year in which there is a February 29.
Would it take light years to finish homework?
A light-year is a unit of distance, not a unit of time.
Is it true that the light year is a unit of time?
It is a unit of time and distance. A light year is the amount of time it takes for a beam of light to travel through space in one earth year, which is 5.9 trillion kilometers. Time : one year, distance : 5.9 trillion km.
